The school system has been trying largely without success to kill the cockroaches that have overrun the high school cafeteria and ultimately ended up in the food.

"We've been very aggressive in calling in these folks (exterminators)," Polk County School Superintendent Dr. William Hunter said. "They were here twice last week."

11Alive received photos and tips about roaches in the food from viewers. The photos show bugs floating in peaches, an antenna sticking out of jello, and roach crawling near the jello cups. Kat Hansbrough is one of the viewers that sent in a tip, "Never in my life have I seen such horrible eating conditions in an institution where children should feel safe," she said.

Tenth-grader Holli Staples was one of the first to spot them.

"It had been cooked into the roll," she said. "What if I had ate it? That's disgusting!"

Holli and fellow student Kellsie Beckom started a petition, asking the school to do something about the bugs.

The cafeteria has been shut down for the rest of the school year. Until then, students will eat prepackaged food or food prepared at cafeterias at other schools.
